After importing MySQL db I can no longer log in to phpMyAdmin
Question
Not paying attention, I exported a database from a MySQL 5.5 server, and imported it into a MySQL 5.1 server. Both via phpMyAdmin.
No errors were reported in any logs. I was also immediately able to browse the database as well.
No other changes have been made to the servers or the software. However, following that event, I am unable to log into MySQL via phpMyAdmin using any available login.
I am able to log in via console, and have dropped the added database with no effect. I have also updated the max_allowed_packet size to 16M per other recommended steps also to no avail.
When I try logging in, I get the following message: "#2006 Cannot log in to the MySQL server".
I have not been able to locate any additional information regarding fixes for this. Any recommendations?
Options currently under consideration:
- Upgrade phpMyAdmin
- Upgrade MySQL (needed as well as required for item 1)

您是否尝试过将max_allowed_packet大小更改为更大的值，例如100M？

I have not been able to determine the exact cause of this issue, but a fresh install of the same version of phpMyAdmin (installed to a new folder) fixed the issue.
Thanks for the willing assistance.
Next up: upgrading the MySQL server.
